your PC is fit for running microsoft word etc. it doesnt meet the minimum requirements for GTA:SA, and certainly not for MTA:SA. its not lag, although the pings you said are actually not good. its your computer struggling to keep up.

you certainly wont have your computer rendering and worrying about the position of 30 seemingly random moving cars (by seemingly random, i mean the spawned cars in GTA:SA have paths, the computer has no idea what you're going to do next) in single player.

they've been saying its a racing mod for 8 months, the deathmatch mod wont be out til the summer.
